which Zing Do you have ?Not that it probably relates are you using windows or make

it connected display in the cut window ?

Have you tried pressing the Function key to turn the laser on F2 from memory you may have to check the manual

were very early in my use of the zing my laser had issue which i suspected was related to a flakie bluetooth connection I never really confirm this but after I changed to usb it was never a issue again ?So if your using bluetooth it maybe worth giving usb a try

its possible that it has failed or the data belt has failed The data belt id the flexible wire that carried the signal to the carriage for the blade up and down and laser light
